RUPTIME(1) BSD General Commands Manual RUPTIME(1)
NAMEruptime -- show host status of local machines
SYNOPSISruptime [-alrtu] [host...]
DESCRIPTION
The ruptime utility gives a status line like uptime(1) for each machine
on the local network; these are formed from packets broadcast by each
host on the network once every three minutes.
If no operands are given, ruptime displays uptime status for all ma-
chines; otherwise only those hosts specified on the command line are dis-
played. If hosts are specified on the command line, the sort order is
equivalent to the order hosts were specified on the command line.
Machines for which no status report has been received for 11 minutes are
shown as being down, and machines for which no status report has been re-
ceived for 4 days are not shown in the list at all.
The options are as follows:
-a Include all users. By default, if a user hasn't typed to the
system for an hour or more, then the user will be omitted from
the output.
-l Sort by load average.
-r Reverse the sort order.
-t Sort by uptime.
-u Sort by number of users.
The default listing is sorted by host name.
